Answer:
8 meter telescope 16 times more gather light than 2 meter telescope.
Explanation:
The amount of light gather by the telescope is known as Light Gathering Power (LGP).
Light Gathering Power is determine by the relation:
In this problem, let l₁ and l₂ be the length of two telescopes and (LGP)₁ and (LGP)₂ be the light gathering power of two telescopes respectively. Then the ratio of their LGP is :
Substitute 8 m for l₁ and 2 m for l₂ in the above equation.
First, convert the given volume in gallons to millliters by the appropriate conversion factors
(13.7 gal) x (3.785 L / 1 gal) x ( 1000 mL / 1) = 51854.5 mL
Multiply this value with the given density to obtain the mass in grams. The operation gives an answer of 38216.7665 g.
Answer:
7.745 feet
Explanation:
Data provided:
Length of the pole, L = 6 feet
Distance between the stake from the bottom of the pole, B = 4 feet
let the length of the rope be 'x'
Now,
The top of the pole, the bottom of the pole and the stake forms a right angled triangle.
Thus,
Using the concept of Pythagoras theorem,
we have
length of the pole as perpendicular, Distance between the stake from the bottom of the pole as base and length of the rope as hypotenuse
therefore,
L² + B² = x²
on substituting the values, we get
6² + 4² = x²
or
x = √60
or
x = 7.745 feet
Answer:
stone A is diamond.
Explanation:
given,
Volume of the two stone = 0.15 cm³
Mass of stone A = 0.52 g
Mass of stone B = 0.42 g
Density of the diamond = 3.5 g/cm³
So, to find which stone is gold we have to calculate the density of both the stone.
We know,
density of stone A
density of stone B.
Hence, the density of the stone A is the equal to Diamond then stone A is diamond.
